Described herein are embodiments of methods and systems for a three mode wireless energy harvesting concept wherein a triceiver system with a single antenna can be configured to transmit wireless data, receive wireless data and exchange power with other devices. When not being used for exchanging power, the triceiver system with the single antenna can be operably connected to data transfer functions of a wireless device. When used for receiving power, the triceiver antenna can be operably connected to subsystems for converting RF signals to electrical energy. When used for transmitting power, the triceiver antenna can be operably connected to subsystems for converting electrical energy to RF signals.
